Most WordPress AI chatbots are text boxes. AI Avatar gives your visitors a real 3D digital human they can talk to with voice — the avatar lip-syncs in real time and replies with natural-sounding speech. Two ways to use Demo mode (this plugin’s default) — Quick evaluation with our hosted demo LLM. Paste the API Key, the chat bubble shows up. No coding required. Ideal for evaluating the 3D avatar quality and the conversation UX. Production mode — Plug in your own LLM (OpenAI, Claude, internal API) via our JavaScript SDK in external mode. You keep full control over the conversation logic and data flow; the plugin / SDK only handles the 3D avatar rendering, lip-sync, and voice I/O. Most production deployments use Production mode so visitor messages never touch our LLM and stay within your existing chat / support stack. The plugin’s bundled chat exists for fast first-impression demos. Why a 3D avatar? More engaging than text — visitors talk longer, ask more questions, convert better Voice in / voice out — natural conversation, not typing Real-time lip-sync — the avatar’s mouth matches the speech, not a cheap GIF Drop-in — one API Key in settings, the bubble shows up in 3 minutes Features One-click embed via WordPress admin — no code editing Configurable position (4 corners), theme (light/dark/auto), primary color, size [yuji_ai_avatar] shortcode for per-page placement Site-wide auto-inject with per-page exclusion list Auto-detects WordPress site language — UI follows your site’s locale Bundled English + Simplified Chinese translations Async script loading — does not slow down your site No tracking, no admin nags, no “Upgrade to Pro” popups How it works Install and activate the plugin Sign up at avataraisdk.com and create an avatar Paste your API Key into Settings → AI Avatar Done — the chat bubble appears in the corner of your site Pricing The plugin is free and open source (GPLv2). The AI Avatar service has a free tier; paid plans scale with conversation volume. See pricing.
